ANTIFREEZING CLOSET.

SPECIFICATION forming part of Letters Patent No. 737,441, dated August 25, 1903. Application filed January 19. 1903. Serial No. 139,557- (No model.)

To all whom it may concern:

Be it known that I, JOHN MOLONEY, J12, a citizen of the United States, residing at Philadelphia, county of Philadelphia and State of Pennsylvania, have invented. .7, certain new and useful Improvement in Antifreezing Closets, of which the following is a specification.

My invention relates to a new and useful improvement in antifreezing closets, and especially that class known as hopper-closets, and has for its object to provide an exceedingly simple and eifective apparatus which will automatically supply water to the tank and when the seat is depressed hold the same therein, with the exception of an overflow, when the water has reached a predetermined level, and when the weight upon the seat is removed the hopper will be flushed with the entire amount of water contained in the tank and valve-box, so as to leave the valve-box, tank, and hopper supply-pipe empty after the closet has been used.

WVith these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawing, forming a part of this specification, in which is represented a hopper of the usual construction and connections in elevation and a vertical section of the tank with my improved apparatus applied thereto.

A represents the hopper, and (J the soilpipe leading therefrom through the ordinary trap 13 to the sewer.

D is a water-supply pipe which passes through the valve E and from thence leads upward through the pipe F to the tank G. After entering the tank this pipe leads into the box H, in which is confined a float I. This float is connected by the rod J to the valve K, which is adapted to close upon the under side of the valve-seat L when the float is moved upward, as will be readily understood. The Valve K is located in the coupling M, to which is connected the flush-pipe N, leading down to the hopper i l the usual manner.

0 is an overflow-pipe having the usual float P for controlling the valve in the upper end thereof, and this overflow-pipe leads to the flush -pipe N through the coupling M, as clearly shown, bel ow the valve K.

From the foregoing description the operation of my improvement will be as follows: \Vhen the seat Q is depressed, the valve-rod R will operate the Valve E in such a manner as to close the openingleading to the drainpipe T to allow t e water from the supplypipe D to pass through the valve into the pipe F and from thence to the heat-box IL Tlm water entering this box at the bottom thereof Will force the float I upward and in so doing will close the valve K, and when the water reaches the top of the float-box it will overflow into the tank G, and the float having previously closed the valve K the water will rise within the tank until the weight is removed from the seat Q, when the rod R will be forced upward by the spring action of the valve E, thus closing the opening leading from the supply-pipe D to the valve and opening the valve to the waste-pipe T. This will allow the water to drain from the box H through the pipe F, waste-pipe '1 into the pipe B, and on to the sewer, and as the water is lowered in the box ll the float I will follow the water downward, and in doing so the valve K will be open and the water in the tank G will rush through the flush-pipe N and accomplish the usual results aimed at in flushclosets. Should the seat Q remain depressed a considerable length of time, the water in rising in the tank when it reaches the floatP will raise said float and open the upper end of the overflow-pipe 0, so as to allow the excess water to flow through said pipe into the flush-pipe N and from there through the hopper to the sewer. This will prevent the tank from ever overflowing.

The bottom of the tank, as is shown, is inclined in both directions to the outlet S, and thus all of the water will flow therefrom, which will remove the possibility of the apparatus freezing, and as a further protection for preventing the freezing of any water within the apparatus the waste-pipe T lay the a tion of the valve E will always hi 0611 when the closet is not being used, and th ere fore all of the water will drain from the pi; pe F through the valve and waste-pipe to the sewer. Thus there will be no Water remaining in the apparatus above the frost-line. 'l' he valve K is not intended to fit the valve-swat L with a water-tight connection, but if so made with recesses K in order as to allow a certaln amount of leakage around the valve when the closet is in use in order that the: hopper may be kept wet.

It will be seen that no accura te fittings are required for the carrying out of my invention and that the entire operations thereof will be automatic, and at any time when the closet is out of use no water will remai 11 in the pipes, tanks, or box, and therefore no freezing of these parts can take place.

My invention is especially apphcable to outdoor closets and entirely overcomes the disadvantage of the waste of "waterwlnch usually takes place in such closets and at the same time accomplishes all Hi the iesnlts desired.

One of the principal adv ntages of my improvement is that it is applicable to hopperelosets as they are now constructed and requires no alterations thereof, the addition being only the pipe F, flush-pipe N, and the tank and mechanism carried thereby.

Having thus fully described my invention, what I claim as new and useful is- In combination, a suitable tank, a pipe extending into the tank, a coupling on the end of the pipe havingadepending hollowportion, a box in the tank supported by and connected to the coupling, a ball in the box, a valvestem secured to the ball and passing through a coupling of the pipe, a valve on the lower end of the stem, a valve-casing secured in the bottom of the box with which said valve coacts, a flush-pipe connected to the valvecasing, a soil-pipe, a seat suitably hinged, a valve-rod depressed by the seat, a double valve on the rod, a valve-casing to which the first-named pipe is connected, at supply-pipe for the valve-casing, a drain -pipe for the valve-casing, valves on the last-named valverod for controlling the supply and drain pipes and a spring under the valve-rod for elevating said rod, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
